In readjusting thetool for the larger use something more is required than the mere changein the size and strength thereof. For

through openings in the rail and plate is a bolt 3, uponwhichis fixed anut 4. i

The invention comprises a pair of jaws 5 and l 6, pivoted between a pairof plates 7, as at a; 'Handles 8, shown partly broken away, have apivotal connection with said aws, by means of couplings 9, similar tothe present construction of devices of this class. At the opposite endsfrom the handles the jaws are provided with beak-shaped cutters 10,theedges of which are of as great a width as the nut 3. The spacing ofthe pivots of the jaws 5 and 6 is such as to" permit the cutters toembrace the sides ofthe nut, as shown in Fig. 1, when the jaws are open.Upon power being applied to the handles the cutters are forced into thesides of. the nut, partly splitting the metal and partly wedging itasunder, until the nut is severed into two parts, which can be easilyremoved from the bolt.

Inthe operation of the tool, especially when it is being'operated at apoint near the ground, or in other awkward position, it is found:advisable to provide a means for steadying the same, so that the cutterswill not slip out of place, or get into a position to improperly performthe work.

herein, shallbe capable of a certain amount which is being severed. Thisis accomplished by means of a block 11, supported between the jaws 5 and6 by pins 12 fixed therein,

of the jaws, as shown inbroken lines, said spaces permitting a limitedmovement of the jaws with relation to the pins. I

. In the outer end of the block 11 is held a guide 15, by meansofathreaded pin 16, enaged in a similarly threaded opening in the end ofthe block, permitting an adjustment It is also essential that thesteadying means, as set out and provided on their outer endswo iwithheads 13, held in spaces 1 1 in the edges of the position of the guide15, so as to accommodate the same to nuts-of different sizes. 'Theguide15 is provided with flanges the nut 4t, and holdingthe head of thetooland cutters thereof in proper position for performingthe operation, andpreventing the guide from slipping on the nut. The pins 12 are insubstantial alignment with the pivots a, and upon the closing movement17 capable of embracing theupper edge of I of the jaws the pins andblock will recede cutters from lateral movement in either digradually,corresponding with the upward rection. movement of the upper part of thenut 4 as In providing the cutters at the ends of the cutting operationproceeds.
